MBR vs. GPT in Windows 11: Which Partition Style Should You Use?
Compare MBR and GPT limits, Windows 11 boot requirements, and conversion risks before initializing, cloning, or changing a disk.
Read guide →Disk management
Understand the layout before changing the partition.
Storage problems can look similar while having very different causes. Inspect first, back up second, and make the smallest necessary change.
Partition operations can make data inaccessible if power fails or the wrong disk is selected. Back up important files and confirm the disk number twice.
A safer sequence
Work through the problem in order.
01
Inspect
Use Windows storage settings and Disk Management to identify what is actually consuming space.
02
Back up
Protect important files and create recovery media before resizing or converting partitions.
03
Change minimally
Prefer reversible cleanup and one change at a time, with verification after each step.
